Multi-Agent Orchestration & Safeguards
One agent is useful. Multiple agents working together is powerful — but dangerous without safeguards. Learn how to build orchestrated multi-agent solutions with approval controls and oversight modes.
Why multiple agents?
Multi-agent orchestration is like a team of specialists working together. Instead of one person doing everything, you have an analyst, a reviewer, a decision-maker, and a communicator — each doing what they’re best at.
One agent might research a problem, another evaluates the findings, a third makes a recommendation, and a fourth presents it to the user. An orchestrator coordinates the whole team — like a project manager ensuring everyone does their part in the right order.
Orchestration patterns
| Feature | Sequential | Parallel | Dynamic Routing |
|---|---|---|---|
| How it works | Agent A finishes, passes to Agent B, then Agent C | Agents A, B, C all work simultaneously | Orchestrator decides which agent to call based on the task |
| Best for | Pipeline processing (extract, analyse, summarise) | Independent sub-tasks (research, translate, format) | Mixed workloads where the right agent depends on input |
| Speed | Slowest (one at a time) | Fastest (all at once) | Variable (adapts to task) |
| Complexity | Low | Medium (need to combine results) | High (routing logic needed) |
| Example | Loan review: extract data, check compliance, generate report | Translate document into 3 languages simultaneously | Customer query: route to billing, tech support, or complaints agent |
Autonomous vs semiautonomous workflows
| Mode | Agent Behaviour | Safeguards | Use Case |
|---|---|---|---|
| Fully autonomous | Agent acts without human intervention | Tool constraints, rate limits, audit logs | Low-risk, well-tested tasks (FAQ answering, data lookup) |
| Semiautonomous | Agent proposes actions, human approves | Approval gates on high-impact actions | High-stakes decisions (financial approvals, medical advice) |
| Advisory only | Agent recommends but never acts | All actions require human execution | New agents in testing, untrusted scenarios |
Approval flow controls
| Control | What It Does | Configuration |
|---|---|---|
| Approval gates | Pause workflow until human approves | Trigger on specific tool calls or conditions |
| Escalation rules | Route to human when confidence is low | Based on agent’s self-assessment or score thresholds |
| Override capability | Human can modify agent’s proposed action | Always available in semiautonomous mode |
| Audit trail | Log every action, approval, and override | Automatic in Foundry tracing |
Real-world example: Atlas Financial's multi-agent loan review
Atlas Financial uses three agents to review loan applications:
Agent 1: Data Extractor (autonomous)
- Extracts applicant data from PDF application using Content Understanding
- Pulls credit score from external API
- Fully autonomous — low risk, no decisions
Agent 2: Compliance Analyst (semiautonomous)
- Reviews application against regulations (Azure AI Search)
- Generates compliance assessment
- Approval gate: If the assessment recommends rejection, a human compliance officer must review before proceeding
Agent 3: Communication Agent (autonomous for approvals, gated for rejections)
- Generates notification to the applicant
- Auto-sends for approved applications
- Approval gate: Rejection notifications require human review of tone and accuracy
Orchestrator: Sequential pipeline — Agent 1 → Agent 2 → Agent 3. If Agent 2 flags a complex case, it escalates directly to a senior analyst (bypassing Agent 3).
Exam tip: Safeguards are not optional
The exam presents autonomous agents as powerful but requiring safeguards. Common traps:
- “The agent should be fully autonomous for all tasks” → Wrong for high-stakes decisions
- “Add approval gates to every action” → Wrong for low-risk tasks (slows everything down)
The correct approach is risk-based: low-risk actions = autonomous, high-risk actions = semiautonomous with approval gates.
Key terms
Knowledge check
A customer asks NeuralMed's patient intake system a billing question. The intake agent specialises in medical appointments, not billing. What orchestration pattern should handle this?
Atlas Financial's compliance agent can autonomously approve routine loans and generate reports. For loan rejections, the legal team requires human review. Which configuration is correct?
